TENSION CHECK-SPRING.

SPECIFICATION forming part of Letters Patent No. 310,426, dated January 6, 1885.

Application filed October 9, 1884.

(No model.)

T0 all whom, it may concern.-

Be it known that I, THoMIs HAMMILL HICKS, residing at the city of Detroit, in the county of Vayne and State of Michigan, physician, have invented certain new and useful Improvements on Tension Check-Springs, of which the following is a specification.

This invention relates to an improvement in tension check-springs; and the invention consists in the peculiar construction and arrangement of the parts, all as hereinafter described.

In the diawings,\vliich accompany this speci` eation, Figure l is a plan view of my in1- proved device. Fig. 2 isacrosssection show ing one of the two guide-plates in elevation.

This tension checlcspring consists of the wire framesA and E, of the guide-plates H D, and of the coil-spring I.

The wire frame A consists of a single piece of wire, bent in the manner shown to form the loops b b and the parallel guide-bars c c. The wire frame E also consists of a single piece of wire, bent in manner shown to form the loop f and the parallel guide-bars g g. The guide-plate H is a metal plate riveted or otherwise secured to the ends of the guidebars g g, while the guide-barscc slide through suitable holes in this plate. The guide-plate D is riveted or otherwise secured to the ends of the guidebars c c, while the guide-bars g g pass loosely through suitable holes in this guide-plate.

I is a coil-spring of suitable tension interposed between the guide-plates D H, its coils passing around the guidebars g g.

L is a leather Hap secured to the loop f, by means of which the device is hooked onto the usual check-rein hook of the saddle or har- HGSS.

In practice the device is equally applicable to side or overhead check-reins, the ends K K of which have to be secured to the loops I) b, as shown.

The advantage of my improved device is that it is strong and simple and not liable to come apart accidentally, as there are two loops for attaching the check rein or reins. The latter can be so arranged that any interference with the horses mane may be avoided.

Instead of one coil-spring, as shown, several coil-springs may be interposed between the guide-plates D H, and kept in place by coiling them around one or more of the guidebars.

Vhat I claim as my invention isl. In combination, the frame A,havingloops b Z) and parallel guide-bars c c, the frame E, having loopf andparallel guidebarsgg,tlieguideplates D H, secured to the ends of the guidel bars of one frame and sliding loosely on the guide-bars of the other frame, respectively, and a coil-spring, I, interposed between the guide-plates, substantially as described.

2. As an improved article of manufacture, a tension check-spring consisting of the frames A E, bent of single pieces of wire, forming suitable loops for securing thedevice in place, guidebars'c c g g, guideplates D H, secured to the ends of the guide-bars of one frame and sliding loosely on the guide-bars of the other frame, respectively, and the tension-spring I, interposed between the guide-plates, all combined substantially as described.

THOS. H. HICKS.
